Abstract : In this paper we concentrate on the second mechanism, but first we comment on a paper by Au and Solymar. That paper shows the real and the imaginary part of the space-charge field for a BSO crystal with frequency detuning as the curve parameter. The curves for higher values of the modulation show kinks which have not been explained by Au and Solymar. We have recalculated these curves for a value of the electron mobility mu three times higher (mu = 0.00001 sq m/Vs), as has been recommended and found not only kinks but even discontinuities. The curves A, B, and C show the absolute value of the space-charge field for modulation as a function of frequency detuning and one has to accept the conclusion that hysteresis is involved.
